GM328 transistor tester ESR meter Cymometer square wave generator

Description:

1 using the latest 2014 version V1.11 software, M328 chip, more features, in addition to the basic functions, as well as extensions.

2 micro-controller uses 8MHz external crystal, measurement accuracy is better.

3 affect the accuracy of one-thousandth of the relevant resistance metal film resistors using the remaining one percent is also used metal film resistors.

4.LCD using 12864 LCD screen that can display measured data and graphics.

5 main chip dual in-line and with a socket, ideal for electronics enthusiasts upgrade or replace the chip.

6 uses 9V laminated battery.

7 All components are made of high quality genuine. LCD screen for low power backlit screen, the backlight current of about 2mA, so the boot time has a backlight for easy use in the dark.

8 Dimensions: 80 (W) X 105 (high) X22 (depth) mm.

9 Weight: about 70 grams.

10 Current: When 9V voltage, stable operating current of about 20mA.

Second technical performance:

A, the basic function

One button operation, automatic shutdown.

20nA shutdown current is only about.

Using 8MH crystals.

Can automatically detect NPN, PNP bipolar transistors, N-channel and P-channel MOS FET, JFET, diodes, dual diode, thyristor small power unidirectional and bidirectional thyristor.

Automatic identification pin arrangement of components.

Current amplification factor and base measuring bipolar transistor – emitter threshold voltage.

You can very by the base – emitter threshold voltage and high-current amplification factor identification Darlington transistors.

Protection diodes can detect bipolar transistors and MOS transistors.

Measuring MOS FET gate threshold voltage and gate capacitance.

Can simultaneously measure two resistors and resistor symbol is displayed. Display with four decimal values on the right side. Resistance symbol is displayed on both sides of the pin number. So you can measure the potentiometer. If the potentiometer wiper not be transferred to a extreme position, it can distinguish between the middle and both ends of the pin.

Resistance measurement resolution is 0.1 ohm, can be measured to 50M ohms.

Can measure capacitance. Capacitor symbol is displayed on the right display values can be displayed with four decimal value. Can measure the capacitance of 30pF-100mF resolution 1pF.

2uF more capacitors can measure the value of the equivalent series resistance ESR. The two values can be displayed with a decimal, resolution of 0.01 ohms.

Two diodes may be displayed in the correct order and a diode symbol, and gives the diode forward voltage.

LED diode is detected, the higher forward voltage. LED combo is identified as two diodes.

The reverse breakdown voltage is less than 4.5V Zener diode can be identified.

You can measure a single diode reverse capacitance. If the connection base and collector of the bipolar transistor or the emitter of a pin, the reverse can also be measured or collector junction capacitance of the emitter junction.

You can get just one measure of the rectifier bridge connections.

Although the capacitance measurement limit is 25pF, but you can be measured by the measured capacitance with a known volume of at least 25pF capacitor in parallel, then the results from measurements in the parallel capacitance obtained by subtracting

To the results.

B. extensions (via menu selection, and the user may want to add a few components for DIY)

1 can measure the frequency of 1Hz-2MHz. Above 25kHz resolution 1Hz, using low frequency periodic measurement resolution can to 0.001MmHz.

2 can measure the DC voltage below 50V.

3 can produce a square wave signal of 1Hz-2MHz.

4 can generate a fixed frequency pulse width but variable pulse wave, short button width by 1% increments, the longer the key width at 10% increments.

5. Separate menu can be activated by capacitance and ESR functions, ranges 2UuF-50mF, since the amplitude of the measured signal is only 300mV, it is possible to measure the road. (Annotation: As a non-4-wire measurement, the measurement of lead resistance may lead to large errors, especially small ESR measurements).

6 by adding a rotary switch for easy menu item selection.

October 14, 2015 Нет нормального описания. Как им пользоваться? Описания предназначения контактов. В принципе аппарат-прибор включился и когда я подцепил транзистор он мне написал что это ДИОД. Может быть я что то не так включил конечно, буду изучать. Но не проще бы какой то мануал приложить?! Пусть на английском языке.

July 31, 2015 Пришёл за 17 дней! На данный момент — это наиболее быстрая доставка из всех что были с «Али» (возможно мне просто повезло). Кроме тестера в комплектации больше ничего нет. Упаковано было не очень надёжно — мало упаковочного материала (при этом посылка слегка пострадала при доставке). Тестер работает, потребовалась небольшая калибровка. Рекомендую магазин! Спасибо!

June 2, 2015 Коробка внешне пришла достаточно помятая, но внутри было хорошо упаковано - все оказалось целым. Экран без защитной пленки и с достаточно глубокими царапинами, но полностью рабочий, так что не критично. В целом работает. Рекомендую. Buyer's reply The film is on the screen, I had not seen it before :)

April 22, 2015 Товар пришёл очень быстро, продавец внимательный. Не было руководства пользователя, продавец отправил на электронку в течении часа после обращения. Всем доволен. Слабовата зажимная колодка, панель для SMD не определяет транзисторы, но это мелочи можно доработать. Продавец хороший
